Comparison

Evaluat vs Web Performance Load Tester

Both tools load-test applications. They go about it very differently. Here's where each one fits, written as fairly as we can manage.

Evaluat

Real-browser performance testing

Evaluat runs each virtual user in an isolated real browser and reports Core Web Vitals, Navigation Timing, and Apdex under load, with session video, network logs, and console logs for every user.

Web Performance Load Tester

Self-hosted load testing

Web Performance Load Tester, from Web Performance, Inc., is a long-established commercial tool you run on your own Windows or macOS machine or in your own cloud account, with flat annual licensing and no per-virtual-user metering. Real-browser load is its heritage, but the current 7.0 release ships HTTP virtual users only, with real browsers returning in 7.1.

The categorical difference: Web Performance Load Tester is a self-hosted load tester you run yourself. Real-browser load is its heritage, but the current 7.0 release is HTTP virtual users only, with real browsers slated to return in 7.1. Evaluat runs a real browser for every virtual user today and reports Core Web Vitals and Apdex as standard.

When Web Performance Load Tester is the right call

Web Performance is genuinely the better tool in a couple of situations.

You want to run the load tester yourself, in your own account. Web Performance runs on your own machine or cloud with flat annual licensing and no per-virtual-user metering, so your data never leaves your environment and cost is predictable at high scale. Evaluat is a hosted service.

You need very high raw HTTP concurrency. Cheap protocol virtual users let Web Performance push far more concurrency per machine than a real-browser-per-user model. If your test is pure HTTP volume, that is a cost advantage.

When Evaluat is the right call

Evaluat runs a real browser today, not in a future release.

You need real-browser metrics now, not in a future release. Evaluat runs a real browser for every virtual user today and reports LCP, INP, CLS, FCP, and Apdex. Web Performance's real-browser load is absent from the current 7.0 release and scheduled for 7.1; today it tests at the HTTP level and does not report Core Web Vitals or Apdex.

You need session video and browser forensics. Evaluat keeps session video, full network logs, console output, and step-by-step pass and fail for every virtual user. Web Performance captures deep HTTP-level detail per user, but no browser session video or console.

You would rather not run and maintain the tool yourself. Evaluat is hosted; you point it at your site and record a journey. Web Performance is software you install, run, and scale on your own infrastructure.

Common questions

FAQ

Does Web Performance Load Tester run real browsers?

Real-browser load is its heritage, but the current 7.0 release ships HTTP virtual users only; real browsers are scheduled to return in 7.1. Evaluat runs a real browser for every virtual user today.

Does it measure Core Web Vitals?

No. Web Performance reports HTTP-level render and timing metrics, not the named Core Web Vitals, and its real-browser mode is not in the current release. Evaluat reports LCP, INP, CLS, and FCP.

Both have an Executive Summary. What is the difference?

Web Performance includes Executive Summary and Performance Goals sections in its reports. Evaluat's Executive Summary is a plain-language verdict with a health score, the key findings ranked by severity, and recommended fixes, generated from the run's Core Web Vitals, Apdex, and errors.

Is Evaluat self-hosted?

No. Evaluat is a hosted service; you point it at your site. Web Performance is software you run on your own machine or cloud account.

Does Evaluat keep a record of every virtual user?

Yes. Every virtual user has session video, full network logs, console output, and step-by-step pass and fail status. When a run regresses you can watch the exact session that failed instead of inferring it from aggregate charts.

Can Evaluat do high-volume HTTP load?

No. Evaluat tests in the browser. For pure HTTP concurrency, Web Performance's protocol virtual users scale further per machine.

Is Evaluat a replacement for Web Performance Load Tester?

For real-browser testing today, with Core Web Vitals and per-session forensics, yes. If you specifically want a self-hosted tool you run yourself, or you are waiting for its 7.1 real-browser release, that is a different preference.
